The title of the television series is taken from W, a fictional webtoon which became a bestseller in South Korea. Authored by Rakesh Aggarwal, the webtoon became a living universe, engendering "two worlds": the real world and the webtoon or W world. The gap between the two worlds is closed as Rakesh's daughter and resident cardiothoracic surgeon Naina Aggarwal gets dragged into the webtoon world, inciting a series of twisted events.
The webtoon world of W is an approximate replica of the real world South Korea and its capital Seoul. Entry to the webtoon world can be through Rakesh's magical tablet, or upon a summoning from the webtoon world or from W's main character Sameer Maheshwari. On the other hand, reentry (through teleportation) to the real world happens also upon Sameer's or the webtoon's bidding, or through a rectangular, crystal-like portal, which appears once Sameer discovers and affirms to himself the truth behind his world and his identity as the main cartoon character. Once the story of the webtoon ends, the webtoon world continues to exist but the "characters" will instantaneously lose their titles as "characters" and may live their own lives.
A Maybank and A Cameron? It's almost like a modern Romeo and Juliet. It's forbidden for them to be together. Could be the end of the world.
The stolen glances, the hidden feelings, the unspoken words, the secret meetings and the obvious hatred towards each other followed by constant conflicts and some hidden past that threatened them but there are always invisible strings tied and pulling them together no matter how hard the tides trying to pull and part them away from each other.
